"PAIA GNOME SYNTHESIZER - Comes with original Construction and Theory Manuals! Very cool rare mono synth controlled by a resistance strip, I little like a theremin... The oscillator plays but the resistance strip does not change the pitch. The resistance strip did change the filter until I swapped out the transistor to try and get the oscillator working (just needs the old transistor, which is included, reinstalled). Also the resistance strip has some small tearing as it was not mounted in the proper enclosure. It does not seem to affect the performance and a new one could easily be made. I'm sure it would be easy for someone with some knowhow to get it functional again."
